Southern Alberta Transmission Reinforcement

The Alberta Electric System Operator (AESO) identified the need to reinforce the transmission system in southern Alberta. Alberta’s electric system needs more capacity to make room for power generated from new wind farm projects proposed throughout southern Alberta. New transmission lines and substations are required to support this growth and collectively these projects make up the Southern Alberta Transmission Reinforcement (SATR).

The AESO filed the need for the SATR in a formal application known as a Needs Identification Document (NID) with the Alberta Utilities Commission (AUC) in December 2008. The AUC is a quasi-judicial agency established by the Alberta government that ensures the fair and responsible delivery of our utility services. The AUC completed a public hearing in Lethbridge to review the need for these projects on June 22, 2009. The AUC approved the need on September 8, 2009.

To learn more about the need for this area development, please visit the AESO website.
